The ratio of BUN to creatinine is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration.
However, there has been research in this area. In germany, frankincense (boswellia serrata) is aparently considered a standard treatment for cancer in brain because it is one of the few substances believed to cross the BBB. Wormwood (Artemisia absinthium) is another possibility.owever, there has been research in this area.

In laboratory animals, no anticholinergic or alpha1-adrenergic-receptor blocking effects were observed. Moreover, no sedative or other central nervous system effects were observed. Radiolabeled tissue distribution studies in rats indicated that fexofenadine does not cross the blood-brain barrier.exofenadine hydrochloride, the major active metabolite of terfenadine, is an antihistamine with selective peripheral H 1 -receptor antagonist activity. Fexofenadine hydrochloride inhibited antigen-induced bronchospasm in sensitized guinea pigs and histamine release from peritoneal mast cells in rats.
